RED670 Line differential protection equipment

The RED670 is a line differential protection device for power systems of all voltage levels to protect, control and monitor overhead

lines and cables. It uses split-phase differential dynamic protection technology, which is highly sensitive to high-resistance faults

and provides safe phase selection for up to five line terminals. In addition, the RED670 can also include two or three winding power equipment.
The RED670 line differential protection device has the following functions:Step by step dynamic protection: RED670 uses step by step

dynamic protection technology with excellent sensitivity and phase selection function to protect overhead lines and cables in the power system.

Adapt to different network structures: RED670 can adapt to different network structures, including impedance grounded or directly grounded systems,

and can protect a variety of networks, including series compensation systems.Current differential compensation function:

RED670 can compensate the current differential of power transformers and other equipment, and this compensation

is carried out in the software algorithm, eliminating the need for auxiliary plug-in current transformers.
